TM3300R Remote Station


The TM-3300 wireless telephone system is designed to meet the communication needs of hazardous gas areas and harsh environments. The TM-3300R wireless remote station is composed of rugged, weatherproof, and intrinsically safe components which are built to withstand industrial use as well as satisfying the requirements for a communication solution in Class 1 Division 2 zones. The TM-3300 system utilizes long-range 900MHz RF technology for transmitting over long distances and through and around many types of obstructions. With the standard antenna, the TM-3300 has a communication range of up to half a mile in open sight. Antenna upgrades are available for extended range or areas of significant obstruction. Proper wiring and or conduit is required to maintain intrinsically safe classification. It can be powered by a solar panel or battery to be used for remote outdoor unpowered non hazardous gas areas.

Single Base & Remote
The TM-3300 is a long-range wireless hazardous area phone system. It is designed for reliable communication with the Class 1 Div. 2 certification. The TM3300 system can work as a stand-alone wireless phone system with or without a CO line.
Multi-Base & Multi-Remotes
The TM-3300 system is flexible because it allows you to expand into a multi-lines phone system. You can combine multi-bases and multi-remotes with a PBX phone system, and the remotes will become the wireless extensions of the PBX. So you can share the phone lines and call between the extensions as an intercom system.
